  • An aerospace requirements setting model to improve system design 
    Tomas Centrich, X.; Shehab, Essam; Sydor, Piotr; Mackley, Tim; John, Philip; Harrison, A. (Elsevier, 2014-10-31)
    Decisions at an early conceptual stage of the product lifecycle, are made with relatively low confidence, but such decisions greatly influence the overall product and service development. It is, therefore, critical to ...
  • Application of NDT thermographic imaging of aerospace structures 
    Deane, Shakeb; Avdelidis, Nicolas Peter; Ibarra-Castanedo, Clemente; Zhang, Hai; Yazdani Nezhad, Hamed; Williamson, Alex A.; Mackley, Tim; Davis, Maxwell J.; Maldague, Xavier P. V.; Tsourdos, Antonios (Elsevier, 2019-02-13)
    This work aims to address the effectiveness and challenges of Non-Destructive Testing (NDT) inspection and improve the detection of defects without causing damage to the material or operator. It focuses on two types of NDT ...
  • Applying systems thinking and aligning it to systems engineering 
    Kasser, Joseph; Mackley, Tim (International Council on Systems Engineering, 2008-06-20)
    This is a paper on thinking about thinking. Systems engineering is an emerging discipline in the area of defining and solving problems in the manner of (Wymore, 1993). The emerging paradigm for problem solving is “systems ...
  • Comparison of cooled and uncooled IR sensors by means of signal-to-noise ratio for NDT diagnostics of aerospace grade composites 
    Shakeb, Deane; Avdelidis, Nicolas Peter; Ibarra-Castanedo, Clemente; Zhang, Hai; Nezhad, Hamed Yazdani; Williamson, Alex A.; Mackley, Tim; Maldague, Xavier P. V.; Tsourdos, Antonios; Nooralishahi, Parham (MDPI, 2020-06-15)
    This work aims to address the effectiveness and challenges of non-destructive testing (NDT) by active infrared thermography (IRT) for the inspection of aerospace-grade composite samples and seeks to compare uncooled and ...
  • Design and evaluation of a novel wastewater treatment package plant 
    Mackley, Tim (Cranfield University, 2007-02)
    The objective of the project was to develop a novel package plant using available process technologies that would be competitive in the domestic waste water treatment market. A market analysis identified the business ...
  • Enhancing service requirements of technical product-service systems 
    Estebanez, L. Ruiz; Shehab, Essam; Sydor, Piotr; Mackley, Tim; John, Philip; Harrison, A. (Elsevier, 2015-10-09)
    Due to the integration of product and services as a new business model, product reliability and strategies for cost reduction at the early design stage have become important factors for many manufacturing firms. It is, ...
  • An integrated aerospace requirement setting and risk analysis tool for life cycle cost reduction and system design improvement 
    Estébanez, L. Ruiz; Shehab, Essam; Sydor, Piotr; Mackley, Tim; John, Philip; Harrison, A. (Elsevier, 2015-10-27)
    In the early conceptual stage of the service orientated model, decisions regarding the design of a new technical product are largely influenced by Service Requirements. Those decisions, therefore, have to merge both technical ...
  • A problem solving method using context types 
    Mackley, Tim (IEEE, 2015-10-26)
    Many shortfalls in problem solving can with hindsight be attributed to applying the wrong approach for the specific problem and its situation or context. Having identified a problem it can then be both a challenge to ...
